Loop check activity is checking entire loop functionality, from field to DCS or Esd or plc or any logical system. It is necesary to check not only continuity of signal, but also range of calibration, alarms, set points and any signal included in the loop folder. For DCS will be tested with hart comunicator or temperature generator, mA. The chapters of Loop Checking: A Technicians Guide are arranged to follow a typical automation project from design checkout at the factory acceptance test (FAT) through to an ongoing sustaining loop performance program. The steps of such projects is as follows: loop checking basics the factory acceptance test (FAT) start-up performance 1/5(1).

Loop Checking means, First we want to check the continuity of cable. Then whether 24 V DC or 4 – 20 mA DC is coming from DCS or JB want to check.

That is called loop Checking. After installation of instruments we must check full loop (instrument-junction box-control room) to ensure that whether the instruments are working properly or not, and.

Everybody knows that loop checking and field instrument testing is the last piece of the puzzle in each project before commencing the commissioning of any system.

It is time-consuming and depends upon the completion of other systems like piping, electrical equipment, control valves etc.
